A Content Template is CKEditor feature that lets you control the structure of the text and preserve consistency across multiple documents. Templates are pre-defined, ready-made document forms with page layout, text formatting and styling as well as other elements.
To use one of CKEditor templates, press the 
button on the toolbar. The following Content Templates dialog window will be displayed on the screen:
The window displays a list of pre-defined templates that are available in your system. The standard installation of CKEditor contains three basic templates, however, this list may be expanded as needed. Since creating and adding new templates is an advanced feature, please contact your system administrator if you need a special template for your purposes.
Each template listed in the window contains a title, an image presenting the schematic outline of the template as well as its description.
In order to select a template, choose it from the list in the Content Templates dialog window and click once. The dialog window will close and the selected template will be applied to the document.
The Content Templates dialog window contains only one configuration option: "Replace actual contents".
Leaving it checked means that the inserted template will also replace the content entered previously into the CKEditor window, deleting it in the process. This is a potentially destructive operation, so if you unintentionally remove the text using this option, you can always revert this operation by clicking the 
button on the toolbar or Ctrl+Z on your keyboard.
If you leave the "Replace actual contents" option unchecked, the template will be inserted in the current position of the cursor in the document.
Figure below shows the editoring area of CKEditor after inserting the template called "Strange Template" that defines a two-column-layout with headings and a text placeholder:
